Injection Timing
1. Remove the stop solenoid.
2. Remove the injection pipes and nozzle.
3. Set the speed control lever to maximum fuel discharge position.
(Reference)
• Turn the flywheel with screwdriver.
4. Turn the flywheel counterclockwise (facing the flywheel) until the
fuel fills up to the hole of the delivery valve holder for 1st cylinder.
5. Turn the flywheel further and stop turning when the fuel begins to
flow over, to get the present injection timing.
6. (The flywheel has mark 1TC and four lines indicating every 0.087
rad (5 °) of crank angle from 0.175 rad (10 °) to 0.436 rad (25 °)
before mark 1TC) Calculate the angle which the center of the
window points out. If the calculation differs from specified
injection timing, add or remove the shim to adjust.
(Injection Timing)
• The sealant is applied to both sides of the soft metal gasket
shim. The liquid gasket is not required for assembling.
• Shims are available in thickness of 0.20 mm, 0.25 mm and
0.30 mm. Combine these shims for adjustments.
• Addition or reduction of shim (0.05 mm, 0.0020 in.) delays or
advances the injection timing by approx. 0.0087 rad (0.5 °).
• In disassembling and replacing, be sure to use the same
number of new gasket shims with the same thickness.
